Recent Progress of Lead Halide Perovskite Sensitized Solar Cells

Low cost organic and inorganic hybrid perovskites such as CH 3 NH 3 PbI 3 has demonstrated a rapid increase in efficiency and has attracted tremendous research effort within a few years.The perovskite solar cells has evolved from traditional sensitized solar cell using liquid iodine electrolyte to solid state solar cell with either mesoporous or planar structure.The morphology controllable solution chemistry deposition of perovskite has progress into 15%～17% efficiency perovoskite solar cells reported by several groups.The perovskite sensitized solar cells has also progress from pure mesoporous structure into meso-planar hybrid one, which has the advantages of high efficiency and better stability.Here we review recent progress on the development of perovskite sensitized solar cells, different band gap perovskites and their deposition, different backbone nanostructures and their charge transfer properties.
